The police watchdog has found no evidence of criminality by officers in the fatal shooting of Mark Duggan.

Sunday marks the two-year anniversary of his death in Tottenham, north London, which sparked a national wave of riots and looting.

The Independent Police Complaints Commission (IPCC) has been investigating whether any of the 11 firearms officers involved in Mr Duggan's shooting committed any wrongdoing.

But a spokeswoman said: "We have found no evidence to indicate criminality at this stage."

Meanwhile, Mr Duggan’s relatives gathered on Saturday with justice campaigners - along with supporters of Joy Gardner and Roger Sylvester who both died after being restrained by police officers - and Cynthia Jarrett, whose death when police raided her home sparked the Broadwater Farm riots in Tottenham in the 1980s.

Mr Duggan's aunt, Carole Duggan, said she wanted the officers involved to be prosecuted.

"It's been two years and we are now waiting for the inquest to get the answers to the questions we have about how and why Mark was killed," she said before the meeting.

"We expect those responsible for Mark's death to be prosecuted and for justice to be served."

Mr Duggan was shot by armed police in Tottenham on August 4, 2011, after marksmen stopped the minicab in which he was travelling.

Officers feared the father-of-four was on his way to carry out a revenge shooting for his cousin's death.

An inquest into the 29-year-old's death is due to start next month following a series of delays.

Local outrage at the police shooting marked the start of a wave of rioting, looting, and arson that spread across parts of the country in the summer of 2011.

The theme of Saturday evening's event was "Justice delayed is justice denied", with the families speaking about their ongoing battles for the truth about their loved ones' deaths.

Ms Gardner, who was facing deportation, died in 1993 after police officers restrained her and gagged her with tape.

Her mother, Myrna Simpson, said: "It's important for people to fight for justice and don't stop, because there is no other way to get justice but to fight for it.

"I am still fighting for justice for Joy and not only for Joy but for all. I am fighting for justice for everyone that has been unjustly killed."
